Random perturbed uniform mesh in Matlab....
Random perturbed uniform mesh in Matlab....
(OP)
Hey guys and gals,
I am trying to generate a random perturbed mesh in Matlab and I an having a bit of problems. Does anyone know any good references that I can use to get an Algorithm or even some sample Matlab code.Or in general any suggestions at all will be welcomed.
Can't wait to see what you'll come up with..

A little more information would be useful

CODE
x = [1:10];
y = [1:20];
[X,Y] = meshgrid(x,y);
% define some constant z values (for 3-D plotting)
Z = zeros(length(y),length(x));
% plot the undeformed mesh
figure;
subplot(1,2,1);
mesh(X,Y,Z);
axis([0 11 0 21 -1 1]);
view([0,0,1]);
title('Unperturbed Mesh');
% define the random perturbations
X_rand = (rand(length(y),length(x))-0.5)./3;
Y_rand = (rand(length(y),length(x))-0.5)./3;
% perturb the mesh
X_p = X+X_rand;
Y_p = Y+Y_rand;
% plot the deformed mesh
subplot(1,2,2);
mesh(X_p,Y_p,Z);
axis([0 11 0 21 -1 1]);
view([0,0,1]);
